I would love to use my Presto 6N as my primary playback turntable, at least for now, as I am on a tight budget. It has a 12" balanced homemade tonearm created by its previous owner out of some sort of copper pipe (!), which I am finding tracks remarkably well, with as little distortion as I have encountered in any turntable of mine. There is no antiskating, so it is a little primitive, but honestly, it sounds great.
So....I'd like to upgrade the quality of the thing over time, and I am fishing for suggestions.
1) The biggest problem I am finding with the thing right now is electrical motor hum/buzz at 60 cycles and its harmonics. That is, the standard Stanton cartridge or wiring is actually picking up some electrical interference from the Bodine motor.
Has anyone run into this problem? What did you do to minimize the hum?
Hi Steve,
Are you sure its electrical? My 6N transmits quite a bit of mechanical noise into the platter. It affects cutting as well as playback. Attacking that is on my "to do" list.
If the hum is electrical, you might be able to kill it with better grounding and shielding. That's always a bit of cut and try.

As Markrob mentioned, improved/repaired grounding or additional shielding may be needed, but it might just be an issue of lead dress. It's possible the wiring from the tonearm may be picking up interference from the power lines or motor just based on its position, and you may be able to reduce or eliminate the hum by moving the position of the wires slightly within the turntable.
